Painted String Rendering

Terry,

My "learning to tune" piano had / has exactly the same characteristic =
throughout the tenor agraffe section.  No paint, but 75 years of rust, =
and conformation of string and agraffe to each other.  After attending a =
David Betts seminar on agraffes at the Arlington convention, I restrung =
two of the worst notes, following David's procedure for cleaning and =
reaming (tool available at Pianotek) the agraffe.  What a difference!  =
Those 6 strings now render as smoothly as any strings on any piano I =
have run into.  I mean to do a couple more strings, leaving the agraffes =
alone, and a couple more agraffes leaving the original strings in place, =
to try to isolate the biggest contributor to the improvement, but =
haven't gotten around to it.

Regarding paint, I am doing some action work on a M&H BB for a dealer, =
which he had restrung by someone else.  There is a lot of gold paint on =
the strings, looks like overspray from touching up the plate.  I have =
tuned this piano, and didn't notice any problems with string rendering.  =
Maybe the paint doesn't extend into the agraffe bearing surfaces, but my =
bets are on rust, conformance, and burrs on the agraffe, not paint.

Good luck selling the restringing job!

Mike

  I indicated in my original post that several times this tuning and on =
previous tunings I have applied a liberal dose of Protek to the string, =
the felt, the agraffe - all to no avail (maybe worked a little less bad, =
but a bad problem still existed - I spent 3 hours tuning that monster =
that was only about 4 cents flat - of course that included crawling =
around looking for buzzes, pondering the sticky string thing, and =
afterward listening to this woman rip through a bunch of Rachmananof =
(sp?) (the whole process was not painful - even 60-year-old tubby bass =
strings don't sound all that bad when you hit them just right and in the =
right order - and my upper tenor section seemed to hold it's tune!).

    Terry,

    I remember someone telling this list that the culprit could very =
well be friction between the strings and it's underfelt. I had a =
Heintzman that was excatly like what you described and I cured it with a =
somewhat generous application of protek on the underfelt.

    Try it out and let us know.

    I tuned a 1940s Baldwin L today. It has always been a nasty piano to =
tune.

    Sounds like we have a good reason to restring. Yes?

    If the customer can afford it GO FOR IT !
